Litchi fruit tree seedling tie type ring incision longitudinal cutter groove and technological method thereof

The invention discloses a litchi fruit tree seedling tie type ring incision longitudinal cutter groove and a technological method thereof. The method comprises the steps of selecting bending pruning seedling growing branches, selecting approach grafting main rooted seedlings, performing ringing on bending pruning branches, treating a bending pruning branch approach grafting main root notch, treating an approach grafting main root seedling notch, preparing an approach grafting main root, agricultural hydrophilic rock wool and liquid medicine, binding a bending pruning seedling rooting position and completing nursery stock treatment after bending pruning rooting. The method overcomes existing defects while the advantages of traditional bending pruning seedlings are achieved, the litchi fruiting period is shortened, the nursery stock quality is improved, on the basis of test comparison, the stable main root can be obtained through a method for seedling approach grafting of bending pruning seedlings with good com
